.SH "DESCRIPTION"
.PP
In addition to the error names user programs define, D\-Bus knows a number of generic, standardized error names that are listed below\&.
.PP
In addition to this list, in sd\-bus, the special error namespace
"System\&.Error\&."
is used to map arbitrary Linux system errors (as defined by
\fBerrno\fR(3)) to D\-Bus errors and back\&. For example, the error
\fBEUCLEAN\fR
is mapped to
"System\&.Error\&.EUCLEAN"
and back\&.
.PP
\fBSD_BUS_ERROR_FAILED\fR
.RS 4
A generic error indication\&. See the error message for further details\&. This error name should be avoided, in favor of a more expressive error name\&.
.sp
Added in version 223\&.

Added in version 223\&.
.RE
.PP
\fBSD_BUS_ERROR_IO_ERROR\fR
.RS 4
Generic input/output error, for example when accessing a socket or other I/O context\&.
.sp
Added in version 223\&.

Unable to connect to the specified server\&.
.sp
Added in version 223\&.
.RE
.PP
\fBSD_BUS_ERROR_TIMEOUT\fR

An operation timed out\&. Note that method calls which timeout generate a
\fBSD_BUS_ERROR_NO_REPLY\fR\&.
.sp
Added in version 223\&.
.RE
.PP
\fBSD_BUS_ERROR_NO_NETWORK\fR
.RS 4
No network available to execute requested network operation on\&.
.sp
Added in version 223\&.
.RE
.PP

.RE
.SH "NOTES"
.PP
Functions described here are available as a shared library, which can be compiled against and linked to with the
\fBlibsystemd\fR\ \&\fBpkg-config\fR(1)
file\&.
.PP
The code described here uses
\fBgetenv\fR(3), which is declared to be not multi\-thread\-safe\&. This means that the code calling the functions described here must not call
\fBsetenv\fR(3)
from a parallel thread\&. It is recommended to only do calls to
\fBsetenv()\fR
from an early phase of the program when no other threads have been started\&.
